摘要: | 本研究主要探讨供应商选择问题,并藉由双边规格下多条生产线的制程能力指标CpkM来选择出拥有较佳制程能力的供应商。本文提供两种检定方法来解决问题,其中,第一种方法将两家供应商的CpkMhat相除作为检定统计量,而第二种方法将两家供应商的CpkMhat相减作为检定统计量。对于两种检定方法,我们皆提供两阶段的假设检定,用以比较两家供应商的制程能力以及检测差距。本文亦提供假设检定所对应的临界值及在要求之检定力下所需的样本数,作为供应商选择的辅助资讯。此外,比较两种方法后发现相减法检定力优于相除法。最后,我们应用一个例子,来说明如何在两家供应商中作选择,并验证此研究的可行性。 In this thesis, we consider the supplier selection problem which deals with comparing two-sided processes with multiple manufacturing lines and selecting the one that has a significantly higher capability value based on the process capability index CpkM. We present two methods to tackle the supplier selection problem, that is, the division method and the subtraction method. For both of two methods, we provide testing hypothesis with two phases for comparing two suppliers’ performance and examining the magnitude of process capability difference between two suppliers. Critical values for testing procedure and sample sizes required for a designated selection power are also investigated. In addition, the results show that the subtraction method is more powerful than the division method. An application example on two-sided process with multiple manufacturing lines is presented to illustrate the practicality of this approach. |
